Quench dynamics in topologically non-trivial quantum many-body systems

Sarika Sasidharan Nair, Giedrius Žlabys, Wen-Bin He +2

We investigate the nonequilibrium dynamics of a groundstate fermionic many body gas subjected to a quench between parameter regimes of a topologically nontrivial Hamiltonian. By fo…

Shortcuts to Adiabaticity in Anisotropic Bose-Einstein Condensates

Chinmayee Mishra, Thomas Busch, Thomás Fogarty

We propose shortcut to adiabaticity protocols for Bose-Einstein condensates trapped in generalized anisotropic harmonic traps in three dimensions. These protocols enable high-fidel…

Bose-Fermi -polaron state emergence from correlation-mediated blocking of phase separation

Felipe Gómez-Lozada, Hoshu Hiyane, Thomas Busch +1

We study fermionic impurities in a one-dimensional lattice bosonic bath at unit filling. Using DMRG and mixed boundary conditions-periodic for bosons, open for fermions -- we f…

Phases and dynamics of quantum droplets in the crossover to two-dimensions

Jose Carlos Pelayo, George Bougas, Thomás Fogarty +2

We explore the ground states and dynamics of ultracold atomic droplets in the crossover region from three to two dimensions by solving the two-dimensional and the quasi two-dimensi…

Engineering impurity Bell states through coupling with a quantum bath

Tran Duong Anh-Tai, Thomás Fogarty, Sergi de María-García +2

We theoretically demonstrate the feasibility of creating Bell states in multi-component ultra-cold atomic gases by solely using the ability to control the inter-particle interactio…

Phases and dynamics of few fermionic impurities immersed in two-dimensional boson droplets

Jose Carlos Pelayo, Thomás Fogarty, Thomas Busch +1

We unravel the ground state properties and emergent non-equilibrium dynamics of a mixture consisting of a few spin-polarized fermions embedded in a two-dimensional bosonic quantum…

Quantum soliton-trains of strongly correlated impurities in Bose-Einstein condensates

Hoshu Hiyane, Thomas Busch, Thomás Fogarty

Strongly correlated impurities immersed in a Bose-Einstein condensate (BEC) can form a periodic structure of tightly localized single atoms due to competing inter- and intra-specie…

High fidelity control of a many-body Tonks--Girardeau gas with an effective mean-field approach

Muhammad S. Hasan, Thomás Fogarty, Jing Li +2

Shortcuts to adiabaticity (STA) are powerful tools that can be used to control quantum systems with high fidelity. They work particularly well for single particle and non-interacti…

Dynamical invariant based shortcut to equilibration in open quantum systems

Mohamed Boubakour, Shimpei Endo, Thomás Fogarty +1

We propose using the dynamical invariant also known as the Lewis-Riesenfeld invariant, to speed-up the equilibration of a driven open quantum system. This allows us to reverse engi…
